1. What is geometry?
Ans. Geometry is a branch of mathematics that studies the properties, relationships, and measurements of points, lines, angles, shapes, and solids in space.
2. What are the different types of angles in geometry?
Ans. In geometry, there are several types of angles, including acute angles (less than 90 degrees), obtuse angles (greater than 90 degrees), right angles (exactly 90 degrees), straight angles (exactly 180 degrees), and reflex angles (greater than 180 degrees).
3. How is perimeter calculated in geometry?
Ans. Perimeter is the measurement of the distance around a two-dimensional shape. To calculate the perimeter, you add up the lengths of all the sides of the shape.
4. What are the main properties of triangles in geometry?
Ans. Triangles have several important properties, including the sum of their interior angles always adding up to 180 degrees, the longest side being opposite the largest angle, and the exterior angle being equal to the sum of the two non-adjacent interior angles.
5. How do you calculate the area of a circle in geometry?
Ans. The area of a circle can be calculated using the formula A = πr^2, where A represents the area and r represents the radius of the circle.
